Yeah, sadly all of the games you have picked so far force you to install, with the smallest install being Heavenly Sword's 2gbs, if I recall correctly.
But don't worry! This is not the case for ALL games, or even most of them. Resistance, Ratchet & Clank, and Uncharted all have no installs, with the latter having no visible in-game loading as well.
So far, it seems to me that Japanese devs generally go the install route (DMC4, MGS4, GT5P, etc.) with the exception being Sega, who has allowed optional installs for games like Valkyria Chronicles and Initial D. Games developed by Western developers, in comparison, generally have no installs, such as the aforementioned Uncharted, Resistance, and Ratchet & Clank, in addition to other games like Army of Two, Madden, etc. Of course, there are exceptions on this side as well, the most notable being GTAIV and Heavenly Sword.
